To all whom 'it may concern.'

. Be it known that I, MILTON A. Lonnr, a citizen of the United States, and a resident of Hatcher Station, county of Quitman, State of Georgia, have invented certainnew and useful Improvements in Fertilizer- Mixers, of which the .following is a full and clear specification, reference being had to the accompanying drawings, in wlnchi Figurev l is a front elevation partly broken away; Fig. 2 is plan view of one end of the machine; and Fig. 4 is a detail view partly in end elevation and partly in vertical section; of the grinder.

This invention has relation to that class of machines adaptedfor mixing in various proportions the several ingredients of. fertilizer compositions, and the object ofthe present improvement is to simplify the means whereby-the.proportions of the several ingredients are varied to insure a thorough mixture of the several ingredients, as more fully hereinafter set forth.

In the drawings, a designates aseries of three hoppers mounted so as to discharge directly into spouts l), each of which is pivot-l ally supportedv at its rear 4end 'upon the frame of the machine and is provided at it's forward end with a forwardly projecting arm c. Attached to each arm' c is a cord or otherfiexible element l which is carried upwardly and forwardly over a beam e, mounted on the frame of the machine, and then downwardly and wound around a drum or'shaft f journaled so as to turn in said beam el l lvlounted alongside of each of the arms c is an upright shaft g whose upper end is provided with a series of longitudinal wings rwhich project radially from the shaft. Aiiixed to the lower end of each shaft g is a gear z' and meshing with these gears z' isa series of gears y' aflixed to a horizontal shaft c. The shaft /c is adapted to be driven by any suitable gearing, to the end that the vertical shafts g shall be simultaneously ro,- tated. It will be observed that each one of the drums j is journaled at a point on the beam e to the left of its corresponding verl i tical shaft g,

an end elevation; Fig. 3 is a shortenin so that the pull on the iiexlble elementv al will normally hold the arm c against the addles or wings li on said shaft g,.so that w en the shafts g are rotated the Awlngs or paddles will knock against the arms cj and thus shake the spouts Znv sufficiently to discharge from their forward ends the' fertilizing materials that are respectively deposited in said spouts from the overhead hoppers. The spouts b are arranged tn discharge into troughs Z, which in turn discharge into a hopper m of a well known type of cylinder grinding machine n. After the mixedingredients are round, they are dis charged in a thorougL 1y mixed and comminuted state from the. spout o of the grinder. v

It will be observed that by raising and lowering the spouts b the speed'and quantity of discharge therefrom canbe varied, whereby the proportions of the ingredients may be readily changed from time' to time as occasion may require.

Having thus described my invention, what I claim is: In a mixer, the combination of a series of hoppers, a spout under each hopper, each spout being pivotally supported at its rear end and provided with a forwardly projecting arm at its front end, an upright shaft alongside of each arm and provided with a series of longitudinal radial wings o r paddles, means for rotating these shafts, means for supporting and adjusting the forward ends of the spouts embodying afie'xble element attached to the fonwa'rd' ends of the arm and extending upwardly and laterally therefrom, the lateral inclination of the flexible v.element serving to hold the arm against the wings or paddles, means for lengthening and the iiexible element to thereby vary the Inclination of the spout, and means for mixing the several ingredients discharged from the spouts.

In testimony whereofI hereunto aiix ni'yy signature in the presence of two witnesses. MILTON A. LOKEY. Witnesses:

W. W. Branson, L. G. BRAIINON.
